Improvement in pessaries



UNITED STATES JOHN KEAN, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN PESSARIES.

Specification forming part of Letters Patent No. 163,87 l, dated J une1, 1875; application led May 11, 1875.

To all whom it may concern:

Be it known that I, JOHN KEAN, of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements inPessary; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it. reference being hadto the accompanying drawings, which form part of this specification.

My invention has relation to surgical appliances; and consists of anvimproved self adjusting and sustaining pessary, syringe, &c.

In the drawings, Figure l is a perspective view, and Fig. 2 a verticalsectional elevation, of the instrument complete.

a a are open-work jaws,.hinged together and to a hollow curved standard,b, at cc. This standard is constructed at its lower end with a leftscrew-thread, b. Hinged to each of the jaws a a, at d d, are arms orcurved rods e e, through the lower united end, e', of whichl passes thestandard b. f is a cup, perforated at its bottom, secured to a curvedstem, g, in the interior ofthe standard b. The end of this stem gisconstructed with a right screw-thread, g1. h Vis a nut working on theright screwthread gl of the rod g, and held in place by engaging, by theshoulder g2, on the nut t', the said nut t' working on the leftscrew-thread b on the standard b. This nutt' is held in place byengagement with the piece e', which, with its arms c, are stationary.

The operation of the parts is as followsthe parts being in the position,as shown in Fig. 2, with the jaws closed and the cup down in place: Byturning the nut i to the right the part b, by reason of the nut workingon the left screw-thread b', is pushed up or advanced, the parts e andnut i remaining stationary, thus opening or expanding the jaws. By turnng the nut h to the left, which, by its connection with the nut t',remains stationary, the rod gis pushed up or advanced, thus raising thecup f.

The application or use of the instrument is as follows-the jaws beingclosed and the cup down close, in place, as shown in Fig. 2: Theinstrument is introduced into the vagina as far as necessary. The nut 'iis then turned to the right, which expands the jaws a a to any extent tosuit the wearer. Thus the instrument is securely held in place in thevagina, and without any external appliances. The cup f is then broughtup by turning the nut h to the left until the mouth of the uterus isreceived into the cup f.

Thus it will be seen that the mouth and neck of the uterus is supportedand held up in place, and theinstrument is self-sustaining and may beadjusted to any desired degree, while in place in the vagina, to suitthe wearer.

The cup being perforated at its'bottom, all excrement from the uterus isallowed to pass ott', and is not in the least impeded by the instrument.

The central part of the instrument being hollow and the cup perforated,it may be readily used as a syringe, or a sponge may be clam pcd betweenthe jaws and inserted into the vagina for any purpose. i

The instrument may be made of any suitable or appropriate size andmaterial or combination of materials.

I am aware that hinged win gs and adj ustable cups have before beenemployed in pessaries or uterine supporters 5 this, therefore, I do notclaim.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The adjustable and self-sustaining pessary composed of hollow curvedstandard b, constructed at its end with screw-thread b', adjustable jawsa, hinged together and to the standard, arms e, united at the lower endand hinged4 to the jaws at the top, perforated cup f, secured to acurved stem, g, constructed at its end with screw-thread g', andoperatingnuts h i, working on screw-threads b g', all

constructed, arranged, and adapted to operate as and for the purposedescribed.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 30th day of April, 1875.
